@Erika Rogers Some great advice by @Mitch Messer. As an add on to Mitch's list, I also noticed that you were missing larger Capex items (roof, boiler, water heater, siding, etc.). If you are setting aside 10% for maintenance (and the property is newer/updated), it's likely a portion of that amount could be for capex and the cashflow might be a little less than projected (please take this with a grain of salt, as I'm just starting to look a bit at Tulsa and have no basis for repair costs, only historical costs in the market that I currently invest in).
I did want to mention that you might want to shop the rate with other lenders/a mortgage broker. Are you using a mortgage broker, or a loan officer at an individual bank? Assuming you'd be looking at a 30 year conventional loan (non-owner occupied), my anticipation is that your rate would be in the 3.25%-3.5% range (I just refinanced yesterday at a 3.75% in an entity, which is always more expensive, rate wise).
